Rovio Mobile is celebrating the fall season with a newly released Halloween edition of its popular Angry Birds iOS game. This latest release finds the vengeful birds battling the evil green pigs through 45 spooktacular Halloween-themed levels of physics-based fun.

Angry Birds is a physics puzzle game in which you launch a variety of projectile-weapon-like birds at the makeshift defenses of a group of sinister pigs. To clear each stage, you must destroy all of the pigs before you run out of your allotted number of birds. The game’s cutesy animations and addictive game play have made it one of the more successful iOS offerings of late.

Angry Birds Halloween Edition continues the pig-bashing fun with 45 levels of pig- and pumpkin-smashing action. There’s also a spooky story line that involves a golden egg of terror. Needless to say, fans of the original Angry Birds games should not be disappointed.
